1.1 本规程涵盖了人员进入或远程检查安装的钢筋混凝土管道的检查和验收要求，如 图。1和 2. 分别地 图1 人员进入检查 图2 远程检查摄像机 1.2 本规范的范围旨在进行安装相关观察，并假设安装前检查已经完成。 1.3 钢筋混凝土涵洞、雨水道和雨水管应按照规范制造 C76号 , C506型 , C507级 , C655码 , 1417号 或 1846/1846米 并根据AASHTO R验收 73.本规范仅适用于重力非压力雨水排水应用。 1.4 除非情有可原，否则应使用人员进入。远程检查可用于直径为30英寸的管道。[750 mm]及以下，除非业主或工程师另有规定。 1.5 手动检查安装管道的通道应遵循OSHA 29 CFR PART 1926 SUB PART AA密闭空间进入规定。然而，本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全和健康规程，并确定监管限制的适用性。 1.6 本规程不包括变形或挠度评估。混凝土管被归类为刚性结构，因为它们在开裂前在荷载作用下不会明显弯曲或偏转。由于这些事实，在评估混凝土管道时，形状评估几乎没有价值。 1.7 以英制/美制或[SI单位]表示的值应单独视为标准值。国际单位如括号所示。每个系统中规定的值可能不完全相等； 因此，每个系统应独立于其他系统使用。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 对已安装的钢筋混凝土管道进行检查，以验证产品的正确安装，并确定用于比较和进一步评估的阈值。 4.2 本规程可作为业主在编制项目规范以及在管道安装后检查期间识别、评估和解释观察结果的参考。

1.1 This practice covers the requirements for inspection and acceptance of installed reinforced concrete pipe by either person-entry, or remote inspection as shown in Figs. 1 and 2 , respectively. FIG. 1 Person Entry Inspection FIG. 2 Remote Inspection Camera 1.2 The scope of this specification is intended for installation related observations and assumes that pre-installation inspection has been completed. 1.3 The reinforced concrete culvert, storm drain and storm sewer pipe shall be manufactured in accordance with Specification C76 , C506 , C507 , C655 , C1417 , or C1846/C1846M and accepted in accordance with AASHTO R 73. This specification shall only be used for gravity, non-pressure storm drainage applications. 1.4 Person Entry shall be used unless extenuating circumstances preclude this type inspection. Remote inspection is acceptable for use for pipe diameters of 30 in. [750 mm] and smaller unless otherwise specified by owner or engineer. 1.5 Access of installed pipe for manual inspection shall follow OSHA 29 CFR PART 1926 SUBPART AA regulations for confined space entry. However, this standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6 This practice does not cover deformation or deflection assessment. Concrete pipe is classified as a rigid structure because they do not bend or deflect appreciably under load before cracking. Due to these facts shape evaluation are of little or no value when evaluating concrete pipe. 1.7 The values stated in either Imperial/US or [SI units] are to be regarded separately as standard. The SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The inspection of installed reinforced concrete pipe verifies proper installation of the product and establishes thresholds for comparison further evaluation. 4.2 This practice is useful as a reference by an owner in preparing project specifications and to identify, evaluate and interpret observations during post installation inspections of pipe.
